Table 1
Unwanted penetration into the office or living space is provided by entrance doors made of steel, equipped with powerful locking devices around the entire perimeter of the door. The parameters and characteristics of such doors are regulated by GOST 31173-2003, which was put into effect in 2004.
The development of standards for metal doors is dictated high demands for a number of reasons: compliance with the parameters of doorways in construction, the performance of security functions, insulating properties, their strength and a number of other parameters. Their observance in the manufacture is necessary for the consumer, otherwise they will not perform the required functions. GOST 31173-2003 gives a fairly wide range of manufacturing parameters from entrance doors indoors to secure doors in expensive houses and cottages. Steel doors are very popular in our country.
The standards are intended for serial and small-scale production, where it is possible to debug technological process in accordance with them, where there is control over their compliance with the use of appropriate methods and confirmation of test results in special centers accredited for the right to conduct them. In individual production, this is difficult to implement. Compliance with standards provides the consumer with the necessary consumer qualities.
Classification of metal doors GOST 31173 2003
classify steel doors according to various parameters: purpose, design, finish, operational and mechanical characteristics, security level. Such a classification allows the consumer to simply select a product with the required characteristics. It also allows certification of steel products.
The classification depends not only on its design features, but also on the configuration of the door block with locking mechanisms. For example, the security level depends on the strength of the block (M1, M2, M3), the complexity of the locks and locking mechanisms. Steel door blocks simple execution(strength class M3) are equipped with class III-IV locks (GOST 5089) and special locking mechanisms, and with class M2 they are equipped with multi-bolt locks on reinforced hinges.
Locks are fastened with screws through gaskets and brackets that press the lock to the leaf, equipped with threads. It is better not to use welding when installing locks, the canvas can lead, and the lock will not close. The size of the door leaf should not exceed 2200 mm in height and 1200 mm in width, and the weight should not exceed 250 kg.
steel door construction
The entire structure is welded from steel. The frame is welded from profiles, on which steel sheets are welded on both sides. The metal on the door leaf must be at least 1.8 mm thick. Profiles can be box-section, U-shaped or from a corner. In some cases, the frame can be reinforced with additional profiles inside it (multipliers), both vertical and horizontal mullions.
The frame is being filled basalt wool, polystyrene or other heat and noise insulating materials. To counteract the removal of the block from the hinges, special pins are installed, which are located in the area of \u200b\u200bthe loops. They do not allow you to wring the door from the hinges and remove it. The pins are installed either in a box or in a web by welding or pressing.
When buying, the consumer has the right to choose the type of finish, material and color, however, GOST 31173-2003 defines reference samples. The choice of finishing materials according to GOST is very wide and varied: from genuine leather to polymer coating. The main thing is that GOST determines the permissible coating quality parameters for each material, below which it is impossible to fall. Output control at the production appearance door is treated with special attention.
The main characteristics of metal doors
The main task of the door block is to provide protection against unauthorized entry into the room. In addition to this task, the door must protect against external environment in the form of cold air masses, as well as noise, and serve for a long time without changing the main characteristics. So, the door block should:
- isolate the transfer of heat or cold from the outside to the inside of the room;
- isolate sounds both from outside and from inside to outside;
- do not let air through;
- serve for a long time and with high quality;
- withstand static and dynamic loads on it.
It is these characteristics with quantitative estimates, given in GOST 31173 2003, that are an indicator of the quality of the produced blocks. According to these indicators, products are accepted at manufacturing plants.
Doors manufactured to the requirements of GOST 31173 2003
Ensuring the main security function is achieved by the composition of the characteristics of the door block (primarily strength) with locking mechanisms and locks, that is, one or another of its execution. The higher the strength class and the class of locking devices and locks, the higher the quotation for the performance of the door unit.
How to install a door block?
Metal doors are installed by specialists of the manufacturer, as they are necessary special tools and materials corresponding to a particular product. In the event that it is built new house, then the project should describe the requirements for the size of the doorway, the expected loads and climatic conditions and building code requirements for the installation of this type of door.
Building codes require unconditional provision of filling the gaps between the door and the walls with insulating material, environmentally friendly and with a long service life. An important point when installing the product, it is necessary to place the door block and junction points in the structure in such a way that “cold bridges” and condensate do not form both inside the product and in the room.
The door unit is fixed in the wall opening through the mounting ears using anchors to a depth of 70-100 mm. The number of anchors should ensure that the block is fixed in the opening. The ears are recommended to be placed along the perimeter of the frame with a distance between them of no more than 700 mm. Before starting the installation of doors, it is necessary to make markings. In the doorway, the central axis is determined, along which the door is installed and the points for the location of the ears and, accordingly, the places of fastening with anchors. Deviations of the door along the horizontal and vertical axes are controlled by plumb and level.
If the buyer decides to install the door himself, the company sends him instructions for installing the unit, indicating all the technological operations for this procedure and the corresponding drawings of the main elements and junctions. The buyer also receives a description of all materials used, including metal, steel grade.
Manufacturer's Warranties
When buying a product, a passport is issued on the GOST door. In it, in addition to size and design features, a certificate of conformity is reflected, a description is given specifications mentioned earlier. And as a standard for all passports, the completeness of the product is included. Completeness of the door unit includes locking devices, door hinges, type of leaf finish, sealing gaskets, door closer and door stop.
At the very end of the passport is indicated guarantee period(at least three years from the date of purchase of the product), which is also indicated in the purchase agreement. In the contract, the manufacturer guarantees the buyer the preservation of all characteristics of the product, subject to the rules of transportation, installation of the product and the rules of operation. The document with which the buyer can dispute certain inconsistencies with the passport data of the product and the warranty period itself is a contract for the purchase of a door unit between the buyer and the manufacturer.
It should be noted that at self installation door block, the guarantee may not be received, since the manufacturer is not able to check the door installation technology. Therefore, we recommend using the services of the installation masters of the company that manufactured your door, or resorting to the services of certified teams of craftsmen.
In conclusion, it should be stated: the standardization of production always leads to an improvement in the quality of manufactured products, an increase in the service life of products, an increase in maintainability, a reduction in the cost of manufacturing a product, and a decrease in its price. Therefore, when choosing such complex product, as a door block made of metal, be guided by GOST 31173 2003.
